I just want to find out if anybody has made a eagle layout of a board without any ttl conversion on it. ie, no serial or usb. I've got a few projects that I want to make, but they don't need any communication access, atleast nothing permanent. I've been looking on the net for boards and I even tried modifying the original ss board schematics, but after changing the schematic I need to repopulate the board and then I can't seem to get it singe sided. I'd like to make the boards myself and I would like to have layout in eagle. Is there such a package available or shall I try again with eagle ?

What are your other requirements, eg do you have a size requirement? Does it need to be compatible with standard shields? Pin order need to be the same?

The simplest way to go would be to etch one of the serial single sided boards that are floating around, and just not use the communications bits. Just install the power section, the microcontroller, the reset stuff etc.

Alternatively, if you have something else in mind, eg trying to get it very small, or have specific pins available (e.g. servo connectors or something) I might be interested in mucking around in Eagle to help out.

1.) You could just build the original Arduino board and not populate the DB9 connector and all the ttl components when you assemble your board. (Shortcut)or2.) When you edit the eagle cad schematic, make sure that the Board and the schematic are not only connected in your project, but that both are open when you edit the schematic. (There is no forward or backward annotation unless both the board and schematic are opened and linked.) If they are both open you should simply be able to delete components in the schematic and look over at the PCB to see them missing from that file too.

I don't really have any specific size requirement, but it would be nice to be able to have a board without the serial stuff (apart from two pins coming from the rx and tx). Also, the pin order doesn't need to be the same and it also doesn't have to be shield compatible. I develop with my arduino but once the project is ready I just want to load it onto one of the smaller boards and then install it in an enclosure.

Mike: Sounds like a good idea. If that works then it should be fine. Thanks

Have you looked at the boarduino? It doesn't have any on-board serial or USB, just headers that you can use if you want or need to. Of course, it has male pins instead of female, so that might require some re-arranging.

The boarduino is listed under the hardware page, I think. It's pretty cheap as a kit and easy to assemble.

I had a look at it and it would work great for what I want to do, but ordering stuff from South Africa over the internet is usually either expensive or a mission. I'd like to make the boards myself.

I need to make more adjusts, but I think it's the smaller board size without serial components (looking it better, I can make it a bit smaller), but Arduino fully compatible.

The sizes:66x84mm original SSS (version2)66x90mm S3v3rino57x76mm TTL version

If you move C5 and C8 closer to the border (near the regulator), you will be able to lower a little bit more the cost, by using standard height capacitors. Everything in the SHIELD area, needs to be low profile (shorter more expensive components).
